Imposing compulsory charges for carrier bags in Wales by May 2011 does not solve the problem.

Retailers up and down the country have made great strides to reduce single-use bags. However, there's no denying that millions are still used. To tackle this, we must raise awareness rather than impose an extra administrative burden on retailers to charge for bags, record the number and account to government all or part of the proceeds. Getting people to want to reuse and recycle is the way forward and while in some areas a charge may be necessary, one has to ask if 5p is enough to make people want to change.
